The listing
- Smart Contract System Design: Architect entire smart contract systems for Ondo's evolving product suite — covering new chain deployments, novel DeFi interoperability and bridging solutions, and DeFi protocols — with security, operability, and long-term maintainability designed in from the start.
- Lifecycle Security & Operations: Own contract security not just at deploy but across the full lifetime of the system — including upgrade safety, administrative controls, and the operational guardrails that keep things safe as they evolve.
- Tooling & Automation: Build tooling and automated systems that let non-technical teammates safely view, monitor, and manage contracts without writing scripts or touching raw chain operations directly.
- Cross-Functional Integration: Connect smart contract design to the rest of the product — helping the web team integrate cleanly, helping operational teams monitor and manage without direct scripting, and ensuring design decisions flow sensibly through to end users.
- Technical Leadership: Serve as tech lead and subject matter expert for blockchain projects, guiding the engineering team toward high-impact, scalable solutions and making sound technical decisions aligned with long-term goals.
- Based in PT, MT, CT, or ET time zones.
- Excellent technical and non-technical communication skills, verbal and written.
- Bachelor's degree in Computer Science, Engineering, or a related technical field.
- 5+ years of software engineering experience.
- 3+ years in blockchain engineering, ideally from another DeFi protocol live on multiple chains.
- Strong competency with Solidity; exposure to non-EVM smart contract languages a plus — particularly Solana.
- Demonstrated ability to design systems, not just contracts — including tooling, automation, security across the contract lifecycle, and the integration points between contracts, applications, and operational teams.
- Proven results building and scaling a DeFi protocol.
- Python and/or TypeScript experience preferred (for building tooling and automation).
- Strong technical grasp and excellent judgment on task prioritization.
- Strong emphasis on understanding the "why" behind requirements and a commitment to defining the "minimum scope."
